Utshintsho kwiiMeko zePond Bottom Kuwo onke amaqonga e-Aquaculture

Kuyaziwa ukuba ulawulo lobulunga bamanzi lubalulekile kwi-aquaculture, kwaye umgangatho wamanzi uhambelana ngokusondeleyo nemeko yomzantsi wedama. Umgangatho ophantsi wechibi uququzelela uphuhliso lwendalo yasemanzini. Eli nqaku liza kugxininisa ekutshintsheni kweemeko eziphantsi kwechibi kwizigaba ezahlukeneyo zenkqubo ye-aquaculture kunye nemilinganiselo ehambelanayo.

Ngexesha lenkqubo ye-aquaculture, ezantsi echibini ngokuqhelekileyo kudlula utshintsho ezine: organicization, ukunciphisa, toxicification, kunye acidification.

Inqanaba lokuqala le-Aquaculture-Umbutho

Kwinqanaba lokuqala le-aquaculture, njengoko ukondla kusanda, ukuqokelelwa kobutyobo, ukutya okushiyekileyo, kunye neendle kumzantsi wedama kukhokelela ekwakhiweni kancinci kwezinto eziphilayo, inkqubo eyaziwa ngokuba yi-organicization. Kweli nqanaba, amanqanaba eoksijini anele. Eyona njongo iphambili kukubola i-sludge kunye nendle ezantsi kwechibi, ukuziguqula zibe ziityuwa ezingaphiliyo kunye nezondlo zokukhuthaza ukukhula kwe-algae kunye nokwandisa ioksijini enyibilikileyo emanzini. Iintsholongwane zeMicrobial zingasetyenziselwa ukunceda ukubola udaka kunye nelindle.

Inqanaba eliphakathi lokufuywa kwezilwanyana zasemanzini—Ukunciphisa

Njengoko i-aquaculture iqhubela phambili, ngakumbi ngexesha lokutya okuphezulu kwezilwanyana zasemanzini, isixa sokutya siyaqhubeka sikhula, okukhokelela ekuqokeleleni ngokuthe ngcembe kwezinto eziphilayo echibini ezidlula umthamo wokuzicoca womzimba wamanzi. Isixa esikhulu senkunkuma ephilayo sibola ezantsi, okukhokelela kumanzi amnyama nanuka kakubi, kwaye singene kwisigaba sokunciphisa apho amanzi ngokuthe ngcembe aphelelwa yioksijini. Ngokomzekelo, i-sulfate iguqula ibe yi-hydrogen sulfide, kwaye i-ammonia nitrogen iguqulwa ibe yi-nitrite. Umphumo wokunciphisa ukuncipha okukhulu kweoksijini emazantsi echibi, okukhokelela kwi-pond hypoxia. Kweli nqanaba, kucetyiswa ukuba kusetyenziswe i-oxidizing agents ukuguqulwa kwezantsi, njenge-potassium monopersulfate compound kunye ne-sodium percarbonate. Ezi arhente ze-oxidizing zinokwenza i-oxidize i-sludge esezantsi echibini, ukunciphisa ukusetyenziswa kwe-oksijini, kunye nokuphucula i-oxidation enokuthi isuse imiba emnyama kunye nevumba.

Emva kwexesha eliPhakathi kweNqanaba le-Aquaculture-Toxicification

Ekupheleni kwenqanaba eliphakathi, ichibi livelisa isixa esikhulu sezinto eziyityhefu, eziquka ihydrogen sulfide, ammonia nitrogen, nitrite, kunye nemethane. Ngokukodwa i-hydrogen sulfide kunye ne-nitrite inokubangela ubunzima bokuphefumla okanye ukufuthanisela iintlanzi, i-shrimp kunye noononkala. Ngoko ke, xa amanqanaba e-nitrite kunye ne-ammonia nitrogen ephakanyisiweyo, kuyacetyiswa ukuba kusetyenziswe i-detoxifying agents ukuze unciphise ezi zinto zinetyhefu.

Inqanaba lokugqibela le-Aquaculture-Acidification

Kwinqanaba lokugqibela le-aquaculture, umzantsi wedama uba neasidi ngenxa yokubiliswa kwe-anaerobic kwezixa ezikhulu zezinto eziphilayo, okukhokelela ekuthotyweni kwe-pH kunye nokunyuka kwetyhefu ye-hydrogen sulfide. Kweli nqanaba, ikalika ingagalelwa kwiindawo ezinodaka oluqokelelwe kakhulu ukuthoba ubumuncu bomzantsi wedama, ukunyusa ipH, nokunciphisa ubutyhefu behydrogen sulfide.
